Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

pyrilamine ↔ food

Moderate Food Interaction

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

High Blood Pressure (Hypertension)

Severe Potential Hazard, Moderate plausibility

CNS stimulants - cardiac disease

The use of CNS stimulants is contraindicated in patients with significant cardiovascular impairment such as uncompensated heart failure, severe coronary disease, severe hypertension (including that associated with hyperthyroidism or pheochromocytoma), cardiac structural abnormalities, serious arrhythmias, etc. Sudden death has been reported in adults and children taking CNS stimulant treatment. Additionally, stroke, myocardial infarction, chest pain, syncope, arrhythmias and other symptoms have been reported in adults under treatment. A careful assessment of the cardiovascular status should be done in patients being considered for treatment. This includes family history, physical exam and further cardiac evaluation (EKG and echocardiogram). Patients who develop symptoms should have a detailed cardiac evaluation and if needed, treatment should be suspended.

Severe Potential Hazard, Moderate plausibility

CNS stimulants - hypertension

CNS stimulant medications have shown to increase blood pressure, and their use might be contraindicated in patients with severe hypertension. Caution should be used when administering to patients with preexisting high blood pressure and other cardiovascular conditions. All patients under treatment should be regularly monitored for changes in blood pressure and heart rate.

caffeine - cardiotoxicity

Like other methylxanthines, caffeine at high dosages may be associated with positive inotropic and chronotropic effects on the heart. Caffeine may also produce an increase in systemic vascular resistance, resulting in elevation of blood pressure. Therapy with products containing caffeine should be administered cautiously in patients with severe cardiac disease, hypertension, hyperthyroidism, or acute myocardial injury. Some clinicians recommend avoiding caffeine in patients with symptomatic cardiac arrhythmias and/or palpitations and during the first several days to weeks after an acute myocardial infarction.
